为解决预调式消弧线圈补偿精度较低和随调式消弧线圈接地点残流较大以及补偿速度较慢的问题,结合预调式和随调式消弧线圈的优点,给出了一种新型全补偿消弧线圈的结构,建立了可控电抗器特性仿真模型以及10 kV电网经新型消弧线圈接地仿真模型.仿真结果表明,该消弧线圈在10 kV电网单相接地故障时主消弧线圈可以迅速投入,补偿大部分电容电流；从消弧线圈在反应时间之后可以微调实现精确全部补偿,兼顾了消弧线圈的补偿速度和补偿精度.%To solve problems of low compensation precision of pre-adjusted type arc suppression coil and bigger residual current and slow compensation speed of grounding point of post-set arc suppression coil, the paper gave structure of a new type of arc suppression coil with full compensation combining with advantages of pre-adjusted and post-set arc suppression coil. It established a simulation model of characteristics of controlled reactor and 10 Kv power network to ground with the new type of arc suppression coil. The simulation results showed that when 10 Kv power network happened single-phase ground fault, the main arc suppression coil can quickly operate, and compensate most of capacitive current; subordinate arc suppression coil can compensate accurately with fine turning after response time. The new type of arc suppression coil can improve both speed and accuracy of compensation.
